Will this fit the vortex venom? Featured Answer

Yes. I used it for that sight

by Wzrd, Verified Owner, March 29, 2019
Will this device fit H&K P2000 v3. Expert Answer

This will only mount on a picatinny rail or on a gun pre-cut for optics. If you do not already have an optic mount on your P2000, it will not mount to your gun.

Great protective shell for MRDS optics by HB, Verified Owner, March 12, 2018
As with all Strike Industries gear, the REX is a solid product at a great price. It comes with a nice set of adapters for various MRDS sights. I used it with a Vortex Venom on a CZ Scorpion Evo. The benefit for that set up is the REX lifts the opti...

Functionally worthless by BippyGamer18, Verified Owner, June 1, 2020
This may be common knowledge that I'm just now learning, but I've found that Strike Industries products look tacti-cool but are completely worthless in real-life use. This SI REX is the perfect example. The first time I mounted the REX, the cross b...

Interesting Shrouded Reflex Mount by Core, Verified Owner, June 24, 2025
The design is interesting and creative, I give it high merits. The shroud is rugged and well designed. The too-less picatinny rail clamp base is really forward thinking, no tools needed. My critical issue with the mount is it not being Delta Point...
